So I did what they asked, and enabled logging, etc...here is their responce:
The channel appears to be tuning normally. Suspect a software issue in JRiver. If you'd like we can take a look at a sample recording and see if anything is out of the ordinary.
I tested this on another friend who has the same setup as me, and he has the same issue, so this is 3 seperate installs with the same problem...granted all using Cox Cable, but the channel tunes in quick TV, just not in JRiver.
